Graphene bone repair

Graphene bone repair could be used to help your body heal itself. The graphene bone repair medical technology comes from Carnegie Mellon University and is at proof of concept stage.

“Researchers have successfully used phosphate graphene as a scaffold, enabling the body’s own cells to rapidly reform the missing or damaged bone and hence to promote bone healing.

Graphene has been shown to assist with the repair of broken bones, according to the Singularity Hub. The medical technology comes from Carnegie Mellon University, where the research team has been led by Stefanie A. Sydlik.

The researchers have tested out an alternate formulation of graphene (graphene oxide). This formation is biodegradable and it has been designed to mimic bone.

The material is also biocompatible and had a favourable degradation rate, meaning that it breaks down as the bone repairs. This is through the graphene-like material autodegrading in water on the timescale of months.

The healing properties relate to the ability of the structure to attract stem cells. Stem cells are cells that can differentiate into other types of cells, and can also divide in self-renewal to produce more of the same type of stem cells.

The material is also mechanically stiff and strong. The overall process is intended to improve how animals, including eventually humans following clinical trials, can repair damage to their skeletons (what is known as osteogenesis). At present the material is a proof-of-concept and further research will be required to assess the ability to aid in the bone regeneration process.”
